Yeah, that team is very flawed.
1) Crucibelle shouldn't be running Zen Headbutt, since it does nothing for Cruci except hitting Fidgit, which isn't going to be doing much of anything in return regardless/you could be using U-turn to pivot into literally anything else on your team.
2) Aurumoth is not abusing illusion to its fullest and is using Surf over Hydro Pump for no reason. Being scared of accuracy leaves you unable to KO things you otherwise would be. You should have stuck with the options given to you by the requester and not change them to be something they didn't want.
3) Again with the being scared of accuracy; use Hydro Pump and Fire Blast. Volkraken hits hard, abuse that. Second, use Analytic. Right now it's just piss-weak.
4) Fire Blast over Fire Fang. It does more damage to any fire-weaks and Fire Fang doesn't threaten steel types as much as Fire Blast.
5) ... Choice Scarf Rapid Spin is just BEGGING for setup. You bet your ass that Cawmodore's gonna come in and set up ALL over you, among other things. Use anything else. Heck, Tomohawk would be perfect here to alleviate some of your crippling Ground weakness.
6) Why do you need Nidoking? You have Crucibelle already for illusion, as stated above, and you could use something else to have some Illusion variety, or another role filled on your team such as a set up sweeper (Which you really SHOULD have but don't). Heck, you could change Aurumoth to Quiver Dance and I'd still recommend another sweeper here.
That's just off the top of my head, by the way. There are more flaws that need to be worked on as well.
